PROCESS FOR MANUFACTURING RESIST COMPOSITION AND PATTERNING PROCESS

摘要

This is to provide a process for manufacturing a resist composition which can prepare a resist composition lowered in coating defects, and
the manufacturing process is a process for manufacturing a resist composition to be used in a process for manufacturing a semiconductor apparatus, the process comprising the steps of:
cleaning a manufacturing apparatus for a resist composition with a cleaning solution;
analyzing the cleaning solution taken out from the manufacturing apparatus;
repeating the step of cleaning and the step of analyzing until a concentration of metal components contained in the cleaning solution becomes 5 ppb or less; and
manufacturing the resist composition by using the manufacturing apparatus after the step of repeating.
